Odd one here. My website's authentication type is LDAP (Active Directory). When a user logs into the site for the first time using his AD credentials, a user record is written into the xoops_users table of the website database, but the user_avatar field is not populated (at all). So when the site attempts to dispaly their avatar you get a fancy red X placeholder since it's trying to load "uploads/" as the image.

Any pointers on where/how to change the php so "blank.gif" is inserted in the field by default when a new LDAP user is added?
